You're absolutely right! And you have a great example in art history to support your opinion! Namely, Pope Paul IV who gave Daniele Da Volterra (aka Daniele Ricciarelli) and Girolamo da Fano to cover the nudity Michel Angelo Buonarotti had painted in the Sistine Chapel.

But I would love to get an answer to my question, sorry to quote myself: "Correct me if I'm wrong, but I thought that nudity and violence had to be checked. And I thought that was because people who were offended by both or either would be spared from being confronted with what they'd prefer to avoid. So how come that people still can see them when you checked one, or both when uploading? Is Renderosity's code not good (yet) ?
How can it be that someone can see a thumbnail of an image (s)he has clearly chosen not to see?"

There are no Borg. All resistance is fertile.
